1.2 Configurations
BMG is a battery-powered ride-on scrubber-dryer, able to clean a wide range of floors and dirt types , collecting
during its forward motion the removed dirt and the detergent solution not absorbed by the floor. The machine
can be powered by 2 individual mono-block 12V batteries, to supply 24V DC to the motors and controls.
BMG is available in 2 models and 3 cleaning versions
56 PRO - Version with membrane control panel. The brushdeck of the 56 version is equipped with one disk
brush.
56 PLUS - Advanced version with integrated touch screen display. The brushdeck of the 56 version is equipped
with one disk brush.
65 PRO - Version with membrane control panel. The brushdeck of the 65 version is equipped with two disc
counterrotating brushes with conveying to the center.
65 PLUS - Advanced version with integrated touch screen display. The brushdeck of the 65 version is equipped
with two disc counterrotating brushes with conveying to the center.
50 BTO PRO - Version with membrane control panel. The brushdeck of the BTO version is equipped with
a central oscillating rectangular pad consisting of a base on which a motor is fixed connected to an eccentric
orbital flange, which in turn transmits the motion to a plate on which the pad is applied.

1.5 General Safety Instructions
Always wear the appropriate personal protective equipment at each intervention.
To avoid short-circuits when working in the vicinity of electrical components: avoid the use of non-insulated
tools; do not place or allow metallic objects to fall upon the electrically powered components; remove rings,
watches and/or clothing with metallic parts that might come into contact with the electrically powered compo-
nents.
Do not work underneath the raised machine without adequate fixed safety supports.
Restore all electrical connections after any maintenance interventions.
When doing maintenance work, switch off the machine using the main switch. Remove the key from the block
and disconnect the battery connector from the electrical system connector.
Avoid contact with moving parts. Do not wear loose clothing or jewellery, and tie long hair back.
Block the wheels before lifting the machine.
Lift the machine with equipment that can sustain the weight to be lifted.
Drain both tanks before transport.
Bring both the squeegee and the brushes to a working position before securing the machine to the transport
vehicle.
The ramp gradient must not be such as to cause damage to the machine as it moves up onto the vehicle.
Make sure the electric brake is correctly engaged after loading the machine onto the transport vehicle.
1.6 How to move the machine
The traction gearmotor is equipped with a built-in electrobrake
that is activated when the key switch is deactivated or the pedal
is released. You can manually override this brake, if necessary,
by reaching the rear right side of the machine and turning the
brake lever upwards. Perform this operation only if you need to
push or pull the machine. Remember to reinsert the brake lever
after moving the machine, turning it downwards. If the electric
brake is not reactivated, an alarm will appear when the machine
is switched on.
